Fort Lauderdale, Florida—Democratic presidential candidate Hillary Clinton hugs Sybrina Fulton, mother of Trayvon Martin, who was fatally shot by neighborhood watch volunteer George Zimmerman in 2012, before giving a May 21 speech at a conference of the Circle of Mothers, for women who have lost children to gun violence. Zimmerman, who was acquitted of manslaughter charges, auctioned the gun that killed Martin for $250,000, drawing criticism that he was profiting from the tragedy.
